What does calendula look like?

Calendula is a bright and cheerful flower that’s typically yellow or orange. Also known as pot marigold, calendula resembles daisies, which makes sense since they’re both in the Asteraceae family. Some say the flower resembles marigolds but it really depends on the variety or cultivar.

What do calendula seeds look like?

Calendula seeds look like little curved letter C’s or tiny snakes or worms in a C shape. They may be green or tan, depending on their maturity, but aim to collect them when they are brown if you have the choice. The seeds develop on the dried, dead calendula flower heads.

When can you harvest calendula seeds?

Calendula seeds are tan in color when they are ready to harvest. You’ll want to let them ripen on the plant if you wish to save seeds for next year. We decided to harvest pot marigold seeds in mid-September when we first found them dried on the dead flower heads.

How to Harvest Calendula Seeds from the Garden

To harvest calendula seeds, follow these steps:

  1. Check your calendula flowers regularly to take notice when the flower heads dry to brown.
  2. Choose a flower head that has visible brown seeds showing.
  3. Gently snap or snip the flower stem to remove the calendula deadhead from the plant.
  4. Place the flower head in a basket or on a paper plate and continue checking other spent blooms.
    • Tip: Leave the green seeds for another day or so until they turn brown and dry.
  5. Collect the rest of the seeds and bring them inside to process.
  6. Gently use your thumb to knock the seeds off of the flower head and onto a paper plate.
  7. Place the seeds in a paper envelope for storage until next season.
  8. Label the envelope with the type, variety, or cultivar of calendula seeds for identification and future planting.

Seed Collecting Tips for Pot Marigold

After saving seeds from the calendula in your garden, consider making yourself a note or setting a digital calendar reminder for planting. Pot marigolds tend to be early starters, so you don’t want to miss the start of spring when you can first work the ground.

Truly, I loved growing chamomile just in the next garden bed over from the calendula. We picked flowers from both to enjoy a sunny herbal flower bouquet this summer. I can’t wait to do it all over again next year!
